The Genesis of Cel-Fi™

The smartphone has changed the lives of people around the world. Yet poor indoor mobile signal reception and dropped calls remain a daily challenge for many mobile subscribers. In fact, more than 50% of cell phone users experience some level of poor-quality indoor coverage. With an estimated 80% of all cellular calls originating indoors, poor or non-existent cellular coverage indoors creates user experience problems, slower download speeds, reduced battery life, and ultimately churn for mobile operators.

When Nextivity was founded in 2006, there was no “intelligent” processor for the indoor wireless coverage market that could meet the stringent requirements underpinning the team’s vision for a new generation of signal boosters. The ideal solution needed to be transparent to, and integrated with, mobile operators’ networks. As a result, Nextivity developed its own family of baseband processors to power its flagship multi-core Cel-Fi® Smart Signal Booster®. Nextivity’s proprietary, proven, and custom-designed third-generation signal processor is the driving force behind its Cel-Fi PRO and Cel-Fi DUO all-digital Smart Signal Boosters designed for use on 3G, 4G and LTE (including VoLTE) networks.

Cel-Fi™ was designed and developed using some of the most advanced radio frequency and signal processing technology in the market today. At its core, the Cel-Fi baseband processors are optimized to process RF signals with incredibly low latency ensuring seamless operation between mobile networks and handsets for all 3G and 4G/LTE technologies and services. Even with this low latency, the Cel-Fi baseband processors are still able to use advanced, multi-tap echo cancellation algorithms and multi-processor system gain control to outperform any legacy technologies and provide mobile operators with an unconditionally network-safe guarantee. This guaranteed performance gives mobile operators the peace of mind needed to deploy Cel-Fi signal boosters en-masse in their networks to solve business and consumer coverage and performance issues.

Nextivity has been awarded 12 patents and has another 15 pending. Of those patents awarded, 3 are for 5GHz Modem Technology, and 9 patents relate to Cellular RF Signal Processing. Of those patents pending, an additional 9 patents are for Cellular RF Signal Processing, 1 patent is for RF Hardware Design, 6 are Software patents, and 2 are Manufacturing and Design patents.

Cel-Fi Products

Cel-Fi QUATRA is a scalable in-building cellular system that is a cost-efficient and easy-to-deploy solution for delivering high quality signal in venues up to 200,000 sq. ft. It is a hybrid solution that combines the best of active DAS and Smart Booster technologies. It operates in off-air mode or can be integrated with carrier small cell equipment and operated in distributed small cell mode, creating a Supercell.

Cel-Fi QUATRA is self-configuring and self-optimizing, distributes RF over Ethernet (RFoE) and leverages Power-over-Ethernet (POE) for ease and accuracy of installation by IT personnel. The system is easy to monitor and manage with the Cel-Fi WAVE Platform.

Cel-Fi PRO improves 3G, 4G and LTE cellular service by eliminating dead zones and dropped calls. With 100dB of gain, Cel-Fi PRO will not only improve cellular service across four (4) concurrent bands, it will also reduce your cell phone’s power requirements and extend its battery life. Cel-Fi PRO covers up to 13,000 sq. ft. (approximately 1,200 m2) of indoor space per system. Cel-Fi PRO systems feature an LCD color interface, are fully self-contained and self-configuring, and require no external antennas or wiring. Simply plug it in to boost indoor cellular coverage.

Cel-Fi PRO is CE and FCC approved. It has been approved by numerous mobile operators and regulatory bodies, and is shipping globally.

Cel-Fi PRO EXA variants feature an external antenna connector to enable the use of an external Donor antenna. A Cel-Fi PRO EXA with an external Donor antenna can thereby acquire an outside signal, allowing it to be used in applications where no signal is present indoors (i.e. cement, metal walls, etc.).

Cel-Fi PRO EXA opens up new opportunities for using Cel-Fi PRO Smart Boosters, when other solutions fail. Cel-Fi PRO EXA enables cellular coverage to hard to reach places by allowing the Cel-Fi Network Unit to be placed, where no service exists.

Cel-Fi DUO improves 3G and 4G LTE cellular service by eliminating dead zones and dropped calls. With 100dB of gain, it will improve cellular service, and reduce your cell phone’s power requirements to extend its battery life. The Cel-Fi DUO covers up to 13,000 sq. ft. (approximately 1,200 m2) of indoor space per system. It’s fully self-contained and self-configuring, requiring no external antennas or wiring. Simply plug it in to boost indoor cellular coverage.

Cel-Fi DUO is CE and FCC approved. It has been approved for use by mobile operators, and is shipping globally.

• Improved Battery Life: Cel-Fi manages the power levels between the cell tower and user devices so that subscriber devices enjoy significant improvements in battery life.

• Ease of Installation: Cel-Fi is a true “Plug and Play” system that doesn’t require the installation of external antennas, bulky coaxial cables or a configuration set-up by the subscriber. In fact, Cel-Fi intelligently and automatically senses and adapts to its environment - including changes made by the Operator or those caused by nearby user equipment like Wi-Fi, or other Cel-Fi devices.

Cel-Fi DUO+ dramatically improves 3G/4G/LTE cellular service by eliminating dead zones and dropped calls. With up to 100dB of gain, it will improve cellular service and reduce your cell phone’s power requirements to extend its battery life. The Cel-Fi DUO+ covers up to 15,000 sq. ft. (approximately 1,400 m2) of indoor space per system. It’s fully self-contained and self-configuring, requiring no external antennas or wiring. Simply plug it in to boost indoor cellular coverage.

Cel-Fi DUO+ is available in multiple configurations for use in The Americas, with FCC and Industry Canada approvals.

Improve 3G and 4G LTE cellular service, eliminate dead zones, and dropped calls with Cel-Fi PRIME. With 80dB of gain, Cel-Fi PRIME will not only improve cellular coverage, it will also reduce your cell phone’s power requirements and extend its battery life. PRIME offers plug-and-play cellular coverage for a room, storefront, kiosk, apartment or similar space, enabling clear and reliable connections within the coverage area – approximately 1,000 sq. ft. In an open space, the coverage bubble can be much larger.

Multi-Band Cel-Fi GO

Cel-Fi GO improves cellular voice and data service by eliminating dead zones and dropped calls. Cel-Fi GO is designed to be an unconditionally network safe drop-in replacement for a traditional bi-directional amplifier (BDA). Cel-Fi GO is NEMA 4 rated, and can be deployed in harsh environments, indoors or outdoors. There are two product versions available, and a variety of band (frequency) combinations, available per region.

3-Band Cel-Fi GO

Cel-Fi GO Mobile and Stationary, can relay up to 20 MHz of one (1) 3G or 4G band at a time. It uses nano-technology to support an IP54 rating, and can be implemented in marine, mobile, or fixed installations. Cel-Fi GO can select the band to relay automatically, or the user can manually configure the band using the WAVE app. Cel-Fi GO Mobile and Stationary is CE-certified, and is available in Australia and Latin America.
